The breathing assembly has a connector inserted within the opening of the floatable body; a fixing cap mounted on the floatable body; a mouth connecting member connected to the connector and providing air to the swimmer's mouth; an air intake check member having an inlet check valve opened only in one direction; and a water intake check member having an outlet check valve also opened only in one direction.

The purpose of the present invention is to develop such a solution that enables a long-term underwater stay without any additional load of heavy equipment, also for people who did not complete any specialist courses.

SUMMARY OF THE INVENTION

The diving system according to the present invention comprises a spherical float inside of which there is a centrally positioned pair of cylinders opposite to each other, having air outlet holes with a plurality of side flow tubes and an air-supply pipe mounted onto each cylinder, joined in a put-over manner with a flexible tube terminated with a snorkel comprising an inhalation and exhalation tube with a mouthpiece, separate inhalation and exhalation tubes; and comprising, in the lower part of the exhalation tube, below an outlet check valve of this tube, a control pump.

It is advantageous when each cylinder comprises a bent air-supply pipe attached to the cylinder in such manner that the tube is pushed over the cylinder with a diameter that is twice the diameter of the pipe, advantageously at the depth of 6/7 of the length of the cylinder.

It is advantageous when the base of the cylinder is a round plane with a centrally positioned hole whose diameter is matched to the diameter of the bottom air-supply pipe which passes through it tangentially.

It is advantageous when the system has two flow cylinders, inlet and outlet ones, with a system of five air-supply pipes with inlet holes located radially and symmetrically at a constant distance from the cylinder.

It is advantageous when the air-supply pipes are parallel to each other, and in contact with each other, inseparably, below the base of the cylinders at an angle of 60°, and then parallel and in contact along the section towards the outlet hole of the spherical case through which they pass.

It is advantageous when the outlet/inlet pipes are assembled with the cylinder by means of connecting pipes which are perpendicular to them and assembled with them undetachably.

It is advantageous when the snorkel has an air control pump in the end section of the exhalation tube below the check valve.

It is advantageous when the air control pump has the form of a flexible sleeve with a diameter of advantageously 2 cm, comprising two check valves, an inlet one and an outlet one.

Thanks to the spherical shape of the floatable body and the air-supply system, the diving system floats on the surface of water thus preventing entry of water into the plurality of pipes while the swimmer inhales oxygen. This solution is safe to use, simple to operate and does not require any servicing by third parties. The pipes comprising a flexible pump enable removing the accumulated saliva and condensed air without surfacing.

DETAILED DESCRIPTION OF THE INVENTION

Diving system according to the invention comprises a pair of cylinders 1, 2 with a plurality of venting pipes located radially and parallel to the cylinders 1, 2. Each of the cylinders 1, 2 has an air-supply pipe bent at an angle of 60°, 3 or 4 respectively. The flow cylinders 1, 2, whose diameter is twice the diameter of the air-supply pipes 3, 4, are pushed over the air-supply pipes to the 6/7 of their depth. At the base, each of the cylinders 1, 2 is assembled around the hole 5′ through which an air-supply pipe 3, 4, respectively, is pushed. The air-supply pipes 3, 4 of the both cylinders 1, 2, parallel to each other, are inseparably in contact with each other below the base of the cylinders, at an angle of 60°, and then run parallel and in contact towards the outlet hole of the spherical case 5. To the external walls of the air-supply pipes 3, 4, above the point of contact of the flexible pipe 7, advantageously of silicone rubber, with the air-supply pipes 3, 4, attached are stabilising ballasts 6 in the form of a disc or torus. The flexible pipe 7 has on its external wall lug elements which overlap lug elements on the external walls of the cylinder ends 1, 2 located outside the spherical case 5, thus sealing the connection between the spherical case 5 and the bottom part 7, 8 of the diving system. Thanks to the lug elements which block the movement of the ballast 6, the ballast 6 does not slip off and holds the spherical case 5 in a vertical position. The air-supply pipes 3, 4, are enclosed in a flexible pipe 7 with any length, advantageously with a length of 5 metres, at the end of which there is mounted a diving snorkel 8 with an inhalation and exhalation tube 9 comprising a mouthpiece 10; and having an inhalation tube 11 connected with the inhalation and exhalation tube 9 and an exhalation tube 12. In the end section, the inhalation tube 11 comprises two check valves, an inlet one 13 and an outlet one 13′. In the bottom part of the exhalation tube 12, terminated with the inlet check valve 12′, the snorkel 8 comprises an air control pump 14 which has a form of a flexible sleeve with a diameter of advantageously 2 cm, advantageously made of rubber, comprising two check valves, an inlet one 12′ and an outlet one 14′, which serves the purpose of removing accumulated saliva and condensed air by squeezing the walls of the sleeve.

While the user is submerged under water, the spherical float 1 floats on the surface of water; the float 1 comprises symmetrically and centrally two cylinders 1, 2 each with a top air flow hole, closed at the base, comprising holes 1′, 2′. The air-supply pipe 3, with diameter adjusted thereto, passes through hole 1′; and the air-supply 4 passes through hole 2′, respectively. Pipe 3 is tangential and parallel to pipe 4. The ends of pipes 3, 4 pass through a hole in the spherical case 5 and are connected in a put-over manner with the flexible pipe 7 terminated with the snorkel 8. Each of the cylinders 1, 2 comprises five holes through which the connecting pipes 15 and 15′ pass assembling the cylinder 1, 2 with the L-shaped pipe 16, 16′.

Air reaches the L-shaped pipes 16 supplying oxygen from above the surface of water by the same being sucked by the spherical float 5. The oxygen gets to the system comprised by the cylinder 1, the air-supply pipe 3 and to the flexible pipe 7, and that way to the diving snorkel 8. The L-shaped form of the pipes 16, 16′ prevents entry of water into the system below the pipes 16, 16′. The exhaled air returns to the outside of the float through the pipe 4 and the cylinder 2. The air flow direction is controlled by means of check valves 13, 13′.

Water accumulated in the inhalation and exhalation tube 9 as well as saliva is removed when the pump 14 is squeezed, which causes the opening of the outlet valve 14′ and closing of the inlet valve 12′ thus preventing the flow of the discharged water and saliva towards the mouthpiece 10. In this manner, the used gets rid of the water accumulated in the snorkel 8 without having to surface.
